INTELRLOCKING SHEET-FILING.

Specification of Letters Patent.

Patented LainZl, 1916.

Application filed March 17, 1909, Serial No. 484,019. Renewed June 2S, 1915. Serial No. 36,914.

To all whom it may concern:

Be it known that I, SAMUEL B. SHELDON, a citizen of the United States, residing at Bethlehem, in the county of Northampton and State of Pennsylvania, have invented new and useful Improvements in Interlocking Sheet-Filing, of which the following 1s a specification.

My invention relates to steel sheet piling and consists in a rolled interlocking section,

particularly adapted to be used withl to permit angular adjustment of the secv tions.

The feature of my invention is the interlocking section A of peculiar form adapted to be arranged as shown alternately with channels, or channel beams, B, of usual form to make up the complete wall. These peculiar sections are preferably formed by rolling from the steel billet at one operation in a series of passes, and consist, as an integral article of the web 1, provided correspondingly at each edge with the two flangesy substantially as shown; one of said flanges is the hook 2 and the other, called the flange 3, is offset from the plane of the web and extends substantially longitudinally. -The hook and the flange thus form on each edge a pocket or groove 5 of a'size and proportions to receive the flange 6 of the channel. The groove may be of the size `shown in Fig. 2 substantially to fit the channel flange, with of course, sufficient clearance for easy driving, or may be enlarged as shown in Fig. 3 to permit angular adjustment of the sections, and to afford a space for packing material to render the joints water tight. The hook 2 is reinforced or thickened at the point 7, and tapers therefrom to its tip. The flange is also reinforced at about the point 8 and tapers therefrom.

In the form shown in Fig. 3, the hook is outwardly inclined to permit the inward and upward swing of the channel flange in angular adjustment, for the same reason the flange 3 may be slightly curved downwardly leaving the recess 9 inits upper surface for the corner of the channel.

My piling is easy and economical to manufacture, convenient for use as it utihzes standard beams, and produces a `strong and compact wall with the webs substantially in alinement.

Having thus described my what I vclaim`is,- A

l. 'Interlocking steel sheet piling sections adapted to .be arranged alternately with channels' to form a continuous wall and comprising each a web and on each edge thereof a hook and a flange, the hook being inclined to the plane of the web and the flange being slightly downcurved from said web to permit a limited amount of angular adjustment to the channels.

2. Interlocking steel sheet-piling sections adapted to be arranged alternately with channel beam sections to form a continuous wall, and comprising each a web and on each edge thereof a hook and a flange, the hook being inclined to the plane of the web and the flange slightly downwardly curved forming an enlarged groove on each edge to receive the channel flange and permit relative angular adjustment of *he adjacent sections, said hooks and flanges being thickened adjacent the web and tapering therefrom.

3. Interlocking steel sheet-piling sections, adapted to be arranged alternately with channels, said sections, comprising a web and on each edge thereof a hook and a flange, the hooks extending on one side of the web and the flanges on the other, said flanges being thickened adjacent to the web and tapering therefrom to their edges and "being offset from the plane of the web so invention,

other, and the flanges being` offset Afrom the web so that, in the completed wall, all the webs may lie substantlally in the same plane, the hooks extending substantially at a right angle tothe wall and the flanges extending substantially parallel thereto. a

5. A wall of interlocking steel sheet piling comprising integral rolled sections`of two forms alternately arranged, one form being structural channels of usual shape, the `other form having a web and on each edge thereof a hookV and a flange the hook ,V

extending substantially at a right angle to the web on one side and the flange extending substantially parallel to the web and offset therefrom on the other side, permitting the webs of the alternate sections to lie substantially in the same plane, said liange being thickened at its base.

6. A wall of interlocking steel'sheet piling comprising integral rolled sections of two forms alternately arranged one form being substantially of standard shape, the

i from the web -n the other side and extending substantially parallel thereto, permittingl thewebs of the alternate sections to lie substantially in the same plane, said flange being substantially elongated beyond the plane of said tip to engage with the back of the channel. i

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. A
